The chief trouble with the ordinary smoking pipe is that liquid-combustionproducts,' as a result of the combustion proceeding from the top downward, "are deposited within the 5 unburnt tobacco with the result that they finally, when the smoking has gone on long enough, accumulate on the bottom of the in this respect. I

The present invention has for its object to prevent the tormation'ot'pipe oil and is characterized principally by the facttha-t the construction of the pipe permits the combus tion of the tobaccoto proceed from below upwards. The liquid combustion products in this way gravitate, as they are formed, down into the burning tobacco, where they are burnt without inconvenience to the smoker.

An embodiment ofthe invention is illustrated in the accompanying drawing. Fig. 1 is a longitudinal section and Figs. 2 and 3 show the pipe viewed from the end and thetop. Fig. 4 is an elevation ofthe lid viewed from the direction of the mouth-piece of the pipe. 7

In the pipe bowl 1, there is inserted a combustion shell 2-, the lower part of which is open and the upper part of which is ro-. vided with a spherical bottom. This bottom is perforated by a series of small apertures 3, thus connecting the interior of the com-' bustion shell with the cavity 4 turned out in the pipe bowl. Extending from this room is the tube 5 which in turn is connected with a mouth-piece 6 of the ordinarytype. In addition, the pipe bowl 1 is provided with a lid 7, in which has been cut out the lighting opening 8, above which there is placed a grate 10 with a number of small holes for supporting the tobacco. In the drawing the lighting opening 8 is shown as being accessible from UNITED STATES OFFICE i the side but atria of course becut out so as to faceany other suitable direction. p 5 When the pipeis to be 'used, the lid 7 is firstj'removed; andtlie combustion shell, 2- is then "lilled -with the tobacco to be smoked.

This beingdo'ne thelid-i's'iagain put on and the-pipe lit'throughthe pe ings; The flame is drawn throughthe holes 9 and lights the tobacco, the smoke. being carried away through the openings 8, the cavity 4,'the tube 5 and to the mouth-piece 6 ofthe pipe.

What I claim is 1. In smokingpipes of the type wherein the combustion proceeds from the bottom upwards, a bowl having an open lower end and being in communication with a smoke conduit, a removable cap-shaped lid at the lower end of the pipe bowl, a grate arranged above and spaced apart fromthe bottom'of said lid to provide a chamber therebetween,

and'a lighting channel in the lid, said channel extending through the wallof the lid from the outside thereof to the chamber between the said grate and, bottom.

2. In smoking pipes of the type wherein the combustion proceeds fromthe bottom upwards, a bowl having an open lower end,

3. A smoking pipe comprising a bowl which is open at the bottom, and the top and a removable cap-shaped lid at the lower end eof lateral parts of which aremade integral with the adjacent part of the pipe stem, a tobacco receiving shell within the bowl, said shell being open at the bottom and having an outer flange at its lower edge, a cap removably fit- ,ted on the lower end of the bowl, a grate arranged at some distance above the bottom of the cap, the arrangement being such that the I grate and the said flange will lie between parts of the bowl and'cap, and'an openingthe combustion proceeds from the bottom up wards, a bowl having an open lowerend, a

removable cap-shaped lid at the lower end of the pipe bowl, a grate located within the lid above and spaced apart from the lower part thereof, and an opening for lighting the pipe, said opening being located in the said lid below the grate, the cap-shaped lid being counter-sunk at its upper edge to form a seat for the grate.

5. A smoking pipe comprisin a bowl ha ing a closed top and an open ottom, a tobacco receiving shell inserted in said bowl and having an open bottom and an apertnred 7 top portion spaced apart from the top of: the bowl, a cap removably seoured to. the open lower end of said bowl, a grate arranged at some distance above the bottomgof: the ea-p said cap having a passage therethrough for lighting said pipe, which passage is looated below the grate, the cap being secured toth'e bowl by an upper fiange on the cap fitting around a lower fl ange on the bowl.

In testimony whereofI aflix my signature.
